A flat iron is the one tool that can straighten, curl, and add a bend — if you own only one hot tool, this is the one. Here are 10 worth buying, each linked to a well-reviewed pick.
My top pick: A 1-inch titanium or ceramic flat iron with adjustable temperature (300-450°F), floating plates, and an auto-shutoff is the one to own — 1 inch is the most versatile width, floating plates grip without snagging, and adjustable heat means you won’t fry fine hair.
